Question

Sonu made an electric circuit (A) with a nichrome wire of length 10 cm. Arun also made an electric circuit (B) with a wire of length 5 cm of the same material and thickness as shown in the figure below. The current flowing in both circuits is the same.
(i) Will the heat produced in both the cases A and B be equal? Explain.
(ii) Will the heat produced be the same if the wires taken by them are of equal length but of different thickness? Explain.

Answer 1

Answer:

1. no
2. no

Explanation:

1. the heat produced is directly proportional to the length and area of cross section of wire
2. the heat produced is directly proportional to the length and area of cross section
